ENVELOP-SEAL.

Specification of Letters Patent.

Application filed April 11, 1910.

Patented Feb. 7, 1911.

Serial No. 554,757.

T 0 (ZZZ whom it may concern:

Be it known that I, SAMUEL E. RnAoLEs, a citizen. of the United States,residing at Kilbourn, in the county of Columbia,State of lVisconsin,have invented certain new and useful Improvements in Envelop-Seals; andI do hereby declare the following to be a full clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to envelop seals of that general class in whichtwo metallic disks are locked or clenched together engaging the flap andthe body of the envelop and holding it closed so that the envelop mustbe mutilated beyond repair in order to gain access to its contents.

The object of this invention is to provide a seal of this character thatwill be simple and cheap in construction and which will be neat inappearance and present smooth surfaces both without and within theenvelop so that neither the contents of the enevelop nor adjacentpackages will be mutilated during the transit of the envelop to itsdestination.

The invention consists of a pair of sealing members one of which issecured to the body of the envelop and is provided with a rivetingportion and the other of which is secured to the flap of the envelopandis provided with fastening prongs which are clenched upon the bodyportion of the envelop by said riveting portion.

In the accompanying drawing forming part of this specification, Figure 1is a back view of an envelop showing my improved seal applied thereto.Fig. 9. is a front view of an envelop with a portion broken away toexpose the seal. Fig. 3 is a section through the seal and envelop. Fig.4 is a plan view of the blank of material from which the disk carried bythe envelop flap is formed. Fig. 5 is a plan view of the blank ofmaterial from which the riveting member carried by the envelop body isformed.

In the drawings, 10 designates the envelop body and 11 the envelop flap.

The seal comprising the subject matter of this invention consists of ariveting member 12 formed from a single blank of material, such as tinor the like, having an annular portion 13 and a plate like extension 14projecting from one side of the annular portion, this plate likeextension being bent over the annular portion and registering with thebore of the annular portion. Formed upon the periphery of the annularportion 13 adjacent the sides of the extension 14 are a pair of spurs1.5 which are bent to project substantially perpendicularly to thereverse face of the annular portion 13, or in other words, to projectupon that side of the annular portion opposite to that side over whichthe extension 14 is bent. The riveting member is placed in the body ofthe envelop with the extension 14- in engagement with the contents ofthe envelop, then the spurs 15 are extended through the body of theenvelop so as to engage the flap when the latter is closed.

The flap engaging disk 16 is formed from a single blank of metal and isprovided with a plurality of spurs 17 which are formed by cutting secantslots 18 in the disk, the meeting of these slots being disposed upon theperiphery of the disk as shown at 19. The spurs 17 extend approximatelyperpendicular to the face of the disk and are so placed as to projectthrough the envelop flap and enter the bore of the annular portion 13,the points of the spurs engaging the extension 14 and being clenched bythe latter when the disk 16 and riveting member are pinched together.

It is clear that the extension 14; presents a smooth surface to thecontents of the envelop and that the outer face of the disk 16 presentsa smooth surface to engage adjacent packages while en route so thatneither the contents of the envelop nor the adjacent packages will bemutilated by this seal.

The manner of fastening the envelop is as follows :The disk 16 is forceddownwardly into engagement with the riveting member as above described,until the prongs of the disk are clenched by the extension 14: upon thebody of the envelop. The spurs 1 5 of the riveting member are now bentover the edge of the disk 16 and serve to lock the riveting member anddisk together so that it will be impossible to remove the contents ofthe envelop unless the flap and body of the envelop are mutilated beyondrepair.

From the foregoing description taken in connection with the accompanyingdrawing, it is thought the construction and operation of my inventionwill be easily understood Without a more extended explanation, it beingunderstood that various changes in the form, proportion and minordetails of construction may be made Within the scope of the appendedclaim.

What is claimed is An envelop seal consisting of a riveting memberhaving an annular portion, and a substantially rectangular plate-likeextension peripherally arranged on said annular portion and bent in aplane approximately parallel with said annular portion, of approximatelythe same cross dimension as the annular portion and registering with thebore thereof, a separate disk arranged upon the outer face of saidannular portion, and having a plurality of spurs struck from its centralportion and engaged through the bore of said annular portion, the pointsof said spurs being clenched by said plate-like extension, and lockingspurs arranged upon the periphery of said annular portion and adapted tobe clenched over said disk.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
